How can I lose face fat?

I'm not sure how old you are, but if you're younger I wouldn't worry too much. You might just have some "baby fat" in your face and you're still growing into it. Talking from personal experience, my face didn't slim out until I was in my mid-20s and now I have super defined features.

first of all, i'm sorry you're feeling down about yourself. <3 remember beauty standrds are made up and they're meant to make us feel bad about ourselves! loving how you look is radical! second, does the rest of your family have a fuller face? you could just be genetically predisposed. i have a chubby face no matter how well i eat or how much i work out, it's the same with everyone in my family. it used to really bother me when i was younger, but now that i'm in my 30s i've grown to appreciate my "baby face" :)

I am in the same position you are — underweight, but with a genetic predisposition towards a “fat” neck. Some of it is left over from losing 40 lbs, but the cast majority is having parents and grandparents with double chins. I’ve been to a cosmetic surgeon and there isn’t a lot of actual underlying fat, so the recommended option is surgery to tighten the skin. Not what anyone wants to hear, but I’ve tried every cream and exercise in the book. It’s hard not be self-conscious, but you’re not alone.
